A Course-Based Undergraduate Research Experience Improves Outcomes in Mentored Research

Travel restrictions, pandemics, economic downturn, and increasing costs in organizing workshops all impact on face-to-face training of undergraduates planning to undertake research. The inability to obtain basic, first-hand information regarding research in practice causes undue stress for students and leads to unrealistic expectations regarding research projects. Here, we describe how a student initiated online workshop, co-designed by a group of undergraduate leaders in conjunction with a panel of international academic researchers, and enabled the delivery of an introductory workshop on research training to meet student needs. Post-workshop, over 80%–95% of the participants rated their understanding of different aspects of research in practice as either being good or excellent. The design of this workshop provides an innovative template, in particular for resource-restricted countries, on how student-initiated workshops with multi-institutional academic collaboration could enhance training in research practice.

Community involvement in addressing the antibiotic crisis

Increasing student interest and success in STEM education is a top priority for many postsecondary educational institutions. One well-documented approach to both priorities is to have students participate in a Course Undergraduate Research Experience (CURE). Faculty from several technical colleges and universities in Wisconsin teamed up with the Tiny Earth organization to offer a CURE to address the search for new antibiotics. Students enrolled in undergraduate microbiology courses engaged in research and participated in community outreach. To involve the community, faculty from various institutions joined an NFL team, the Green Bay Packers, and created the Tiny Earth in Titletown symposium. Here, students presented their work via scientific posters, to community and industry members, and networked with other scientists from around the region. The Tiny Earth in Titletown symposium started in 2018, was held again in 2019, and returned in 2022 following a 2-year hiatus due to the COVID-19 pandemic. Record attendance in 2022 suggests that community outreach and education may be helping restore trust in science that was lost during the pandemic.

Breaking the habit: isolating nicotine-degrading bacteria in undergraduate microbiology teaching labs

Nicotine is a major alkaloid in tobacco plants and an addictive component of tobacco products. Some bacteria grow on tobacco plants and have evolved the ability to metabolize nicotine. As part of our microbiology teaching lab, we used minimal media with nicotine as the sole carbon source to isolate nicotine-degrading bacteria from tobacco leaves and commercial tobacco products. Students then identified these bacteria using 16S rRNA sequencing and biochemical assays and assessed their ability to catabolize nicotine using UV spectroscopy. Students were able to isolate and identify 14 distinct genera that can metabolize nicotine. This modification of the commonly used unknown project gave students firsthand experience using selective media, and students got the opportunity to work with largely uncharacterized microbes with a real-world connection to public health, which increased student engagement. Students had the opportunity to think critically about why nicotine-degrading microorganisms associate with tobacco plants, why there are different bacteria that use the same specialized metabolism, and how these organisms are isolated from other bacteria using selective media.
